Improve model readability by displaying signal attributes, such as data types and dimensions, in the block diagram. You can use simulation software to evaluate a new design, diagnose problems with an existing design, and test a system under conditions that are hard to reproduce, such as a satellite in outer space.

In simulink, it is very straightforward to represent and then simulate a mathematical model representing a physical system. If you check block reduction, simulink coder software responds to each signal path as follows. Using these representations you can model mechatronic systems, control software, signal processing algorithms, and communications systems. Examples of commands that change these properties follow this table see examples of setting block properties.
